Abstract
The radiation dose from the first generation EMI scanner has been analysed, including the variation of the dose perpendicular to the section, the dose dependence of the size and collimation of the beam, and the fraction of radiation passing the patient and utilized for information. The possible dose in case of malfunctions of the scanner was also measured.
摘要
已对第一代EMI扫描仪的辐射剂量进行了分析，包括垂直于切片方向的剂量变化、光束尺寸和准直的剂量依赖性，以及穿过患者并用于获取信息的辐射比例。还测量了扫描仪出现故障时可能产生的剂量。
